Measurement Management Systems
Specifies requirements for the management of measurement processes and metrological confirmation of measuring equipment. Replaces ISO 10012:2003.
ISO 10012 specifies requirements for the management of measurement processes and metrological confirmation of measuring equipment used to demonstrate conformance to specified requirements. It ensures measurement results are fit for purpose and that measuring equipment meets stated metrological requirements.
The standard is applied by manufacturing organisations, utilities, calibration laboratories, and any sector where measurement accuracy is critical to product or process conformance. The 2026 revision updates requirements to reflect current metrology practices and digital measurement systems.
ACI-certified auditors assess metrological management systems, evaluate calibration programmes, and verify that measurement uncertainty is understood and managed across measurement processes.
